Bug description: feof no longer detects SSL connections closed by the server
Description:
------------
It seems that there were changes introduced after PHP 4.3.6, the feof
function is no longer returning true when the server closes the SSL socket
connection after transmiting all the contents.
This seems to make it impossible to determine if there was a real network
error or the server closed the connection normally breaking the
compatibility of scripts that rely on feof to determine the end of
connection condition.
This seems to be a revival of bug 25939. It happens under PHp 4.3.2,
4.3.3, 4.3.4 and 4.3.7 . I does not happen under PHP 5.0.0RC3 .
Although I could only reproduce it for SSL connections. It may be
affecting normal TCP connections but I could not yet produce a test script
to demonstrate it consistently.
Reproduce code:
---------------
<?php
$socket=fsockopen("ssl://www.openssl.org", 443, $error);
if(!$socket)
{
echo "socket opening error\n";
exit;
}
echo "connection opened\n";
if(!fputs($socket, "GET / HTTP/1.1\r\nHost:
www.php.net\r\n\r\n"))
{
echo "socket writing error\n";
exit;
}
while(!feof($socket))
{
$data=fread($socket, 1000);
if(!$data)
{
echo "socket reading error\n";
exit;
}
echo "read ",strlen($data)," bytes\n";
}
echo "reached the end of data\n";
fclose($socket);
?>
Expected result:
----------------
connection opened
read 574 bytes
reached the end of data
Actual result:
--------------
connection opened
read 574 bytes
socket reading error
